Abstract

322,515. Holman, J. L., and Holman, K. J. Sept. 5, 1928. Percussive drills. - The pistons of reciprocating tools, such as rock drills, pneumatic hammers, riveters, caulkers, &c. have an outer annular portion 13 which provides a part or the whole of the rubbing face, and is made, in whole or part, of lighter material than the body of the piston. The annulus may be threaded on to a flanged part of the piston 11, and a rifle-nut or other retaining member is threaded into the annulus. Various other methods of attaching the annulus and riflenut to the piston are described. The annulus may be made of fibre &c.
